4. Cyclic adenosine monophosphate (cAMP)-dependent protein kinase (PKA) deficiency on the red blood cell membrane of peripheral blood, cAMP may be a regulator of cell growth and differentiation, cAMP-dependent PKA deficiency in patients with psoriasis, expressed in fibroblasts and red blood cells On the membrane, suggesting a defect in the cAMP-dependent protein kinase signaling system in psoriasis
Its side effects are mild and moderate skin irritation, such as itching, burning sensation, erythema, desquamation, and dryness. These reactions are related to the dosage and dosage form of the drug. They are not durable and can be tolerated. Long-term and large-scale administration can cause teratogenicity

Abstract

The invention belongs to the field of pharmacy and particularly relates to a pharmaceutical composition for treating hyperproliferative skin disease and a preparation of the pharmaceutical composition. The pharmaceutical composition comprises the following components by weight percent: 0.001-0.01% (W / W) of calcipotriene, 0.05-2% (W / W) of tazarotene and 0.05-2% (W / W) of adrenocortical hormone.

Description

technical field [0001] The invention belongs to the field of pharmacy, and relates to a pharmaceutical composition and a preparation thereof for treating epidermal hyperproliferative diseases. Background technique [0002] Epidermal hyperproliferative diseases refer to a group of diseases and disorders characterized by higher than normal levels of epidermal cell proliferation and often also by abnormal differentiation. Psoriasis is a typical epidermal hyperproliferative disease. It is a chronic inflammatory skin disease characterized by epidermal KC hyperproliferation and granulocyte infiltration. The severity of symptoms varies from small local plaques to the whole body. Clinically, it is divided into four types: vulgar, pustular, arthropathic and erythrodermic, among which the common type is the most common type in clinical practice. The disease affects 2% to 3% of the total population, and is one of the most common autoimmune diseases in the world. It can occur at any ag...
